Use your brain in everything
In the math activity class, the teacher asked a question on the blackboard: How can I find the volume of potatoes? I was dumbfounded as soon as I saw this question. Thought: Although I have learned calculation methods for finding volume, they are all about finding the volume of regular objects such as cubes, cuboids, cylinders and cones, and cannot be applied to irregular objects like potatoes. How to find the volume of potatoes? I was scratching my head and thinking about it, but I couldn't figure out a way. The other students were also discussing with each other like a group of little sparrows, trying their best to think of ways to solve the problem, but they couldn't figure it out. When the teacher saw this situation, he reminded everyone: "You can cut potatoes into regular objects, such as cubes, cuboids, cylinders and cones. Wouldn't it be easier to calculate? Of course, if there is an easier method, it can be Use."
I came home after school, put down my schoolbag and hurried to the kitchen to find a potato. Following the teacher's instructions, I cut and cut with a knife, measured and measured with a ruler, and calculated again and again until there were calculation papers all over the floor. Finally, I finally calculated the approximate volume of potatoes. I think this method is too complicated and the calculation is not accurate. Is there a simpler method? I held the potato and thought and looked and looked. When I tilted my head, I suddenly saw the water glass on the table. I had an epiphany. Yes, I can first find a cylindrical cup, then pour an appropriate amount of water, and then put the potatoes into the cup. At this time, the water will rise, and the volume of the water after rising will be no more than the original volume. Is it the size of a potato? Therefore, if you want to find the volume of potatoes, just ask for the volume of the rising water column. Not to mention how happy I was when I figured out this method!
Through the above method, we can get a method for calculating the volume of irregular objects. At the same time, it also made me realize that if I want to learn mathematics well, I have to use my brain more and work harder. Then I will be able to learn mathematics well. It is possible to find more scientific solutions to different mathematics problems, and it is also possible to do other things. in this way.
Use your brain to think about problems
One day at noon when I was doing math homework, I encountered a difficult problem. The title was "A piece of rectangular paper is meters long and wide. When making paper flowers, How many square meters are used for this piece of paper? "At first, I thought it was a cuboid, but I found that I was wrong. I think we should first calculate the area of ??the rectangular paper before we can find out how many square meters it takes to make the paper flowers. I think the formula should be like this: "× Let "×100," equal 45 square decimeters. I suddenly felt that if I do it with my heart and think with my brain, I can do a good job on a question.
During class in the afternoon, Teacher Le handed out homework. There was a question in it. I saw that half of the class got it wrong. The question was "(+) ×" and I calculated it many times. They are all equal to 1. I think it’s better to ask Teacher Le during class what to do. During class, Teacher Le talked about that question in class, and it turned out to be like this.) What is the score? I think many people would say "mixed numbers", but that's wrong. Let's recall that mixed numbers are composed of integers and proper fractions! And ( ) is an improper fraction and should be converted into ( ). "( )＋(
)" is equal to 2. Now you should suddenly realize it!
Through these two things, I found that as long as you think carefully, no problem can stop you. As long as you do every question with your heart and think with your brain, I believe you will succeed. Just like a famous saying, "The habit of thinking when you encounter problems is more important than anything else. The sooner you develop it, the better!" The habit of thinking about problems is almost a characteristic of some smart people who love to learn. If you keep thinking and seeking answers, you can After completing a question well, I hope that those students who don’t usually like to use their brains to think will definitely develop this habit of using their brains to think.
come on! come on!
When reading, you must use your brain diligently
"Read thousands of volumes, and write like a god." People cannot live without reading, and they must learn knowledge from books. However, when you read When reading, have you used your brain? Have you understood it with your heart?
Gorky once said: "Reading is good, but you must remember that a book is just a book. You have to move it yourself." It’s all about the brain.” Some people read a lot of books, but when you ask them what they gained, they don’t know what to say. These people obviously don’t use their brains when reading and read with their heart. This will be useless. Like Newton who discovered gravity, why did he have doubts about getting apples from trees and create science? It was because he used his brain. The same is true for reading. You must be good at using your brain.
Looking over it, how should we use our brains? Of course, we must fully understand the content and ideas in the book. In the process of reading, we must understand the entire content of the book and what it is going to tell us. What kind of inspiration does the story give us! Rather than like some people think; just clarify what the book is about. Our grandma Bing Xin, she has read a lot of books, and she is good at summarizing every time she reads. Summarize and carefully memorize important words and phrases. Later, her works were very popular among primary and secondary school students across the country because she incorporated the knowledge she had accumulated over the years into them and was able to find happiness in the books. "There are poems and books in her belly." "Qi comes from China", it is this effect.
"It is better to gain something by looking at it broadly than by reading it carefully and thinking deeply." Zhu Xi's words let us know more about the great benefits of using your brain when reading. Use your brain and be full of content. Read books carefully to enrich your life and make yourself a thoughtful "gentleman"; broaden your horizons and the boat of knowledge will travel far and wide.
Reading requires diligent use of the brain
"Reading thousands of volumes, writing is like a spirit." People can't live without reading in their lives, and they must learn knowledge from books. But when you read, do you use your brain? Do you understand with your heart? (Ask Sentence form to introduce the topic)
Gorky once said: "Reading is good, but you must remember that books are just books, and you have to use your own brain." Some people also read on a daily basis. They have read a lot of books, but when you ask them what they gained, they don’t know what to say. These people obviously did not use their brains and read with their heart when they were reading. This will be useless. Like discovering La (A) Newton of gravity, why did he have doubts about apples falling from trees and create science? It was because he used his brain. The same is true for reading. You must be good at using your brain.
When we turn over the book, how should we use our brains? Of course, we must fully understand the content and ideas in the book. In the process of reading, we must understand the entire content of the book, what kind of story it is going to tell us, and what kind of gift it has to us. Inspiration! Instead of just clarifying what the books are about, as some people think. Our grandma Bing Xin has read a lot of books. Every time she reads, she is good at summarizing and summarizing, and carefully sums up the important points. Memorize the words and sentences. Later, her works were very popular among primary and secondary school students across the country, because she integrated the knowledge she had accumulated over the years into them and was able to find happiness in the books. "The spirit of poetry and calligraphy in her belly is self-sufficient", which is exactly This effect.
"It is better to gain something by looking at it broadly than by reading it carefully and thinking carefully" (appropriate quotation). Zhu Xi's words let us know more about the great benefits of using our brains in reading. Use your brains and be full of fine books. Enrich your life and make yourself a thoughtful "gentleman"; broaden your horizons, and the boat of knowledge will continue to travel far.
